What is Selinexor?
Selinexor, the active ingredient in Nexpovio, is a selective inhibitor of nuclear export (SINE) presented as an oral tablet for oral use. It is indicated for relapsed or refractory multiple myeloma in combination with dexamethasone and bortezomib. GNH USA supplies Nexpovio as a licensed, GDP‑compliant international pharmaceutical supplier serving oncology centres worldwide.
What is Selinexor used for?
Selinexor acts on malignant cells by blocking nuclear export pathways, making it a key therapy in certain blood cancers. - Relapsed or refractory multiple myeloma: improves disease control when combined with dexamethasone and bortezomib. - Relapsed or refractory diffuse large B‑cell lymphoma: used with standard chemotherapy regimens to enhance response rates. - Relapsed or refractory solid tumours (clinical investigation): evaluated in trials as part of combination strategies to overcome resistance.
What are the side effects of Selinexor?
Selinexor is associated with a range of adverse reactions that vary in frequency and severity.
Common Side Effects: - Fatigue: persistent tiredness affecting daily activities. - Nausea: upset stomach often occurring after dosing. - Thrombocytopenia: reduced platelet count leading to easy bruising. - Anemia: low red blood cell levels causing weakness. - Neutropenia: decreased neutrophils increasing infection risk. - Decreased appetite: reduced desire to eat.
Serious or Rare Side Effects: - Severe infections: opportunistic or bacterial infections requiring hospitalization. - Hepatic dysfunction: elevated liver enzymes or hepatitis. - Cardiac arrhythmias: irregular heart rhythms, especially in patients with pre‑existing conditions. - Pulmonary embolism: blood clot in the lungs. - Tumor lysis syndrome: rapid tumour cell breakdown causing metabolic disturbances. - Hyponatremia: dangerously low sodium levels.
What precautions apply to Selinexor?
Before initiating therapy, clinicians should evaluate several safety parameters. - Monitor blood counts: regular CBC to detect cytopenias. - Assess liver function: periodic LFTs to identify hepatic toxicity. - Evaluate infection risk: avoid use in patients with active uncontrolled infections. - Review concomitant QT‑prolonging agents: consider ECG monitoring. - Pregnancy: risk unknown; avoid unless benefits outweigh potential harm. - Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.
What does Selinexor interact with?
Selinexor may interact with other medicines, altering its efficacy or safety profile.
Major Interactions (Avoid): - Strong CYP3A4 inducers (e.g., rifampin): may reduce Selinexor exposure. - Strong CYP3A4 inhibitors (e.g., ketoconazole): may increase toxicity risk. - QT‑prolonging drugs (e.g., amiodarone): can exacerbate cardiac rhythm disturbances.
Moderate Interactions (Monitor Closely): - Anticoagulants (e.g., warfarin): monitor INR for bleeding risk. - Other antineoplastic agents metabolized by CYP3A4: adjust dosing as needed. - Immunosuppressants (e.g., cyclosporine): watch for enhanced myelosuppression.
